Routh-Hurwitz Stability Criteria Table Generator (ALL CASES)

This function goes through the process of setting up a Routh-Hurwitz table to determine information regarding the in/stability of a system.

This function goes through the process of setting up a Routh-Hurwitz
table to determine information regarding the in/stability of a control
system given a closed/open-loop transfer function. More specifically, this
will solve for and output how many closed/open-loop poles are in the
right-half plane, the left-half plane, and on the jw-axis. Additionally,
this function will take into account and generate the Routh_Hurwitz table
given two special cases:
1)First element of a row is 0.
2)Entire Row is 0.

Recall that this function operates under the assumption that you are
inputting a CLOSED LOOP TRANSFER FUNCTION. Later developments will
incorporate inputs of open loop forward transfer functions with unity
and/or nonunity feedback.

UPDATE 1.1: This program now takes into account UNITY feedback.
